Successful Project
Solar Resilience: Overcoming Clouds and Snow for a 400W Office Solution
Last week, Mr. Cleves called one of our team experts about the solar power modules. Do you know where we start?
We asked him about the requirements. That is the first station where we get the idea!
Guess what? He took time and told us high requirements. These were:
- 400-watt off-grid solar panel with excellent low-light performance.
- High performance of 400-watt solar panels with Pole mounts and ground mounts.
- High efficiency to fulfill his power needs at the office.
That was a short list! Oh, here comes our team. To qualify every single aspect, we asked him about the WEATHER conditions! And here, the problem reaches its peak!
He had most of the Cloudy days, leading to LESS power generation in the low light conditions. Plus, his area was around the mountains. overseeing insufficient capacity for WIND LOADS and high snow!
But we said no problem; we have the SOLUTIONS to cope with such conditions.
We turned up hundreds of RELIABLE suppliers on our list. Thoroughly match their features! And boom!
We got him the exact 400-watt off-grid solar panel he needed. We even shipped him.
Do you know why he chose us?
Many reasons:
- Excellent quality of 400-watt off-grid solar panels.
- The high warranty period of 10+ years.
- High efficiency of solar cells.
- Premium support!
You are waiting for what? Hit us a message right away!
